a be first term and d be common difference

a+a+2d+a+4d+a+6d+a+9d=17
5a+21d=17--(1)

And

a+d+a+3d+a+5d+a+7d+a+9d=15
5a+25d=15--(2)

Eq(1)-Eq(2)

-4d=-2
d=1/2

Put in second one

5a+25d=15
a+5d=3
a+5/2=15
a=15-5/2
a=25/2

What is 7 8/13 rounded to the nearest whole number?

vfiekz [6]

Answer: The answer would be 8.

Step-by-step explanation: I'm going to assume you mean 7 8/13 is a mixed fraction. So you multiply the denominator, 13, multiply 7 to that, then add 8 to it and the denominator would be the same as before. That should give you 99/13. When you divide, you get around 7.6, rounding closest to 8.
